   ROOTPASS WELDING — Mobile welding & fabrication, Piedmont Triad
   Third voice. Shares nothing with the other two builds:
     · full-bleed colour BANDS, not an editorial grid or soft cards
     · Space Grotesk — engineered letterforms, not condensed, not serif
     · safety orange as a structural block, not a hairline accent
     · a real quote FORM — the conversion device neither other demo has
   Built by 72Frame.
